All solved
Not sure exactly but on the PW7 Setup (remote) you can toggle off power management so that covers it.
However, I toggled it back on a little later and problem no longer there.
I think it might have something to do with me using the 5 BNC while I had a HDMI from Freeview (DVD Recorder) connected to VP50.
I was hoping no HDCP would be implemented for Freeview but there is - maybe broadcast but more likely just the player.
Either way, a couple of problems cleared themselves up once the HDMI was disconnected and boxes powered down and rebooted.
No more HDMI in my setup until I connect to a screen that way
